Maybe they're vikings.. a grave where a viking was buried with all his armor, weaponry, jewels, even sometimes with his horse and/or boat.. was called kuml !
But these look ok to me as non-painted. Invocation of Nehek and they're just out of the grave kind of stuff going on here :D
Good thing they were buried with weapons. It's always such a hassle to have to put a guy in the graveyard handing out equipment as they rise. (as for the minis they need some grass or dirt to be rising out of...)
